Math Functions
Example
The following example shows how to create a custom measurement that is based on the values from
other measurements. The example calculates the 3-Dimensional Euclidean distance between the center
of a hole and the center of the base of a nearby stud, then checks decision limits on this metric before
sending the output.
/* Calculate the 3-Dimensional Euclidean distance between two points in 3D space*/
/* Retrieve 3D coordinate from Hole X, Y and Z tools (assumes these tools have been
configured as ID 0, ID 1 and ID 2 respectively) */
double HoleX = Measurement_Value(0);
double HoleY = Measurement_Value(1);
